Baltimore Orioles second baseman Brian Roberts is expected to be sidelined 2-4 weeks because of a ruptured tendon in the back of his right knee, according to The Baltimore Sun. He has been placed on the 15-day disabled list.

Roberts suffered the injury while stealing second base during Thursday’s win over the Tampa Bay Rays. He immediately left the game, creating speculation that he was destined for yet another long layoff.

Because of concussion problems and other injuries, Roberts has been limited to a total of 115 games over the previous three seasons.

In three games this season, Roberts is 5-for-12 with an RBI and a stolen base.
